HANGER-CLAM P FOR TROLLEY-WIRES.

SPECIFICATION forming part Of Letters Patent No. 674,656, dated May 21, 1901.

Application filed December 28, 19QO. Serial No. 41,388. (No model.)

To all whom it may concern: pressed tightly together to'securelyclamp and Be it known that I, GEORGE HENRY RIOKE, hold the said wire between them.

a citizen of the United States of America, and The parts or members 1 of the wire-clamp aresidentof Cincinnati,in the conntyof Hamare formed on their outer surfaces with con 5 ilton and State of Ohio, have invented certain trally-located strengthening or stiffening ribs new and useful Improvements in Hanger- 4, which extend down to the lower parts of Clamps for Trolley-Wires, of which the folthe clamping-jaws 2, and the upper portions lowing is a specification. of said members 1 are thickened to form This invention relates to certain 'improveshanks 5, which are each 'made of semicircu- 1O ments in wire-clamps such as are employed lar cross-section and are adapted to fit tofor holding trolley-wires and the likerand gether when the .two parts or members of the the object of the invention is to provide a declamp are assembled to produce a tubular vice of this character of a simple and inexpart, as shown in Figs. 2 and 4, which part pensive nature and of a strong and durable is formed with exterior screw-threads 6 to 15 construction having improved devices adaptenable it to be screwed into a nut 7, herein ed for securely clamping and holding the wire, shown as formed with a hexagonal upper part while permitting of ready operation to release adapted to receive a wrench or other tool the wire, so as to facilitate repairs. whereby it may be conveniently turned.

By this means it will be seen that as the nut 7is turned and screwed down upon the shanks 5 of the clamping members and comes into engagement with the shallower portions 12 of the screw-threads 6 on said shanks the space between the flanges or ribs 13 at the lower portions or clamping-jaws 2 of the members will permit the said lower portions or jaws to be pressed by the wedging action of the nut forcibly upon the opposite sides of the trolley-wire w, so as to securely clamp and hold the said wire. The socket 8, formed in the upper parts 5 of th e'members', also affords a convenient means to receive the bolt or other part by means of which the improved Wire-clamp is suspended.

Fromthe above description it will be seen that the improved wire-clamp is of an extremely simple and inexpensive nature and affords a secure means for holding the trolley-Wire, While permitting of its being readily actuated by merely unscrewing the not 7 to release the wire from the clamping engagement of the jaws 2 therewith, so that repairing is greatly facilitated. When desired, also, the clamping members 1 maybe readily disengaged from the nut 7 and replaced with little difficulty. It will also be obvious from the above description of my improvements that the improved wire-clamp is capable of some modification without material departure from the principles and spirit of the invention, and for this reason I do not wish to be understood as limiting myself to the precise form and arrangement of the several parts of the device herein set forth.

Having thus described my invention, what I claim, and desire to secure by Letters P at ent, is-

1. In a wire clamp, the combination of members having clamping-jaws to impinge upon a wire and formed with hollows adapted to correspond, when the members are held in relation, to produce a socket the walls of which are screw-threaded, a part having wedging and screw threaded engagement with the outer sides of said members to press said jaws forcibly upon the wire, and a bolt having at its lower end threaded engagement in said socket, substantially asset forth.

2. In a wire clamp, the combination of members having clampingjaws to impinge upon a wire and having strengthening flanges or ribs upon their inner surfaces, said flanges or ribs being spaced apart adjacent to the clamping-jaws and being fittedfiush one on the other at the other end of the wire-clamp and a part having wedging engagement with the outer sides of the members to press said jaws forcibly upon the wire, substantially as set forth.
